"__attribute ((packed))" must be defined for unions, in order to make
sure that the compiler packs unions.
|
|
|
|
|
| |
The caller explicitly specifies CM2 and CM3, rather than one blob
containing both.
|

The msgb_*_push() functions erroneously returned the firsrt byte after
newly-pushed information, which makes no sense at all.

The same functions are e.g. required by the NITZ code in 04.08, and we
don't want copy+paste.

We need to keep the old one for compatibility !

The SMR process is used to transfer SMS TPDUs. It is now extracted from
OpenBSC. It includes a real state machine now for easier debugging.
Also it implements the TR1M and TR2M timers. The memory notification
procedure is missing, but not required for network side.

Timing advance and power level indicated by MS (measurement reports)
and BTS (SI 5/6) are now stored for use at ACCH data link connection.
This is part of a set of commit to fix LAPDm to handle datalink
connection on ACCH (SAPI 3)
This is required to transfer SMS on SACCH of TCH/f or SDCCH/8 (4).

Instead of mixing together the GSM layer 1 interface and RSL interface
with the implementation of LAPD, the core function of LAPD is now
extracted from LAPDm. The core implementation is now in lapd_core.c
and lapd_core.h respectively.
The lapd_core.c implements exactly one datalink instance for one SAP.
The surrounding implementation "lapdm.c" codes/decodes the layer 2
headers and handles multiplexing and datalink instances, as well as
translates primitives from/to RSL layer.
lapd_core.c can now be used for other LAPD implementations. (ISDN/ABIS)

Additionally it wasn't possible to send concatenated sms from the vty.
To send multiple sms, it is necessary to use padding bits and add a user_data_header.
Therefore the gsm_7bit_encode function was splitted to gsm_7bit_encode and gsm_septets2octets.
gsm_septets2octets: this is the old gsm_7bit_encode function + additional padding parameter
Additionally the gsm_7bit_decode function was modified to take account for the user_data_header.
With the new gsm_get_octet_len function you can get the octet length for a given septet length.
I also added several sms tests.

This had broken lcr compilation...

This could be used to submit SMS to OpenBSC and to get informed
about new SMS coming from OpenBSC.

This was introduced by me in commit

If we encounter a tag with 0xFF, we overflow our existing tlv_parse
array definitions.
Warning: this breaks ABI

those two are used in the RSL SACCH FILLING messages and delivered
like SI5 / SI6.

The idea here is to use the osmocom core primitive code ot abstract out
primitives for inter-layer comunication in GSM.

(otherwise 'struct value_string' would not be defined)

This file is using enums in that might or might not be
known to the compiler. Forward declare them.

warning: array ‘abis_nm_obj_class_names’ assumed to have one element
|
|
|
|
|
|
|
|
| |
and export the underlying raw value_string arrays instead:
abis_nm_obj_class_names / abis_nm_adm_state_names.
This permits the caller to use get_string_value() as well as
get_value_string().
